an experiment was conducted to compare stability of two product lines. assume yields of each product line follow normal distribution. a study measured two product lines for 10 days: product line 1- sample variance 25, product line 2- sample variance 12. conduct the hypothesis test and determine if it can be concluded that the variance of product line 1 is larger than product line 2. =.02 H0: 1^2 = 2^2 H1: 1^2 > 2%2
